Product overview

Released on August 29, 2017, the SFX L Power 600W is be quiet!’s SFX‑L entry in the SFX L Power family, pairing a longer SFX‑L shell with a 120 mm fan and fully modular cabling. It’s an 80 Plus Gold unit with single‑rail 12V output, four 6+2‑pin PCIe leads, and a 3‑year warranty. Classed as high_end for PSUs, it exists to give quiet, tidy cabling and reliable 600 W power to compact builds where a 120 mm fan helps noise and thermals. Best fit is SFF mini‑ITX/compact ATX systems and mid‑range gaming GPUs that use 6+2‑pin PCIe power; note it lacks ATX 3.0/3.1 and native 12VHPWR connectors. Discontinuation status is not confirmed.
